Vitamin D helps in avoiding colds and flu. People with vitamin D deficiency are more likely to suffer from cold and flu in comparison to those who have sufficient levels of vitamin D.[1] Sunlight is a great source of vitamin D.

When there is a loss of the bone mass or the density of bone minerals become poor, a patient is often prescribed to increase the calcium intake.[4] However, reality may be that the body is unable to absorb it due to insufficient Vitamin D. Along with growing age, the mineral density of bones become lower. In order to combat this, adequate calcium intake along with vitamin D is also important.

5. Respiratory Issues

Adequate levels of vitamin D may cause respiratory disorders and diseases. It may cause lung diseases and asthma. As the immune system becomes weak due to insufficient amount of the vitamin, its anti-microbial and germ-protecting ability goes down, which gives rise to diseases like tuberculosis and respiratory infections.[5]
